The Clackamas County sheriff’s department has placed three schools on lockdown, as officers search for a suspect in a knife attack near Lake Oswego.

Officials have placed Lake Oswego High School, Lake Oswego Junior High and Forest Hills Elementary School on lockdown as a precaution during the search. Sergeant Adam Phillips of the Clackamas County Sheriff’s Office says some nearby pre-schools are also choosing to follow lockdown procedures.

At around 6:30 Monday morning, officers received a 911 call from a home near Lake Oswego, reporting the attack and describing the fleeing suspect. He is described as a white male, 6 feet tall, with a brown beard, slender build, and wearing a head wrap.

Residents in the area are asked to call 911 if they spot the suspect. Parents should contact the school district for instructions on lockdown procedures.
